Application iled January 2, 1917. Serial No. 140,174.

T0v all whom t may concern.'

Be it known that I, EUGENE G. REISING, a citizen of the United States,residing at East Hartford, in the county of Hartford and State ofConnecticut, have invented a new and Improved Firing-Pin for Firearms,of which the following is aspecification.

My invention relates to the class of devices that are employed infirearms to strike the cartridge and cause its explosion; and an objectof my invention, among others, is to provide a device of this class thatshall be simple and durable in its construction and particularly one inwhich the firing tip may be readily removed from or replaced on the mainpart of the pin.

One form of deviceembodying my invention and in the construction and useof which the objects herein set out, as well as others, may be attained,is illustrated in the accompanying drawings, in which- Figure 1 is adetail view in central longitudinal section through a breech-boltcontaining my improved firing pin.

Fig. 2 is a side view of my improved firing pin with parts thereof cutin central longitudinal section.

Fig'. 3 is a detail side view of'a portion of the body of the pin.

In the accompanying drawings the numeral 5 indicates a breech-bolt thatmay be of any ordinary material and constructed in any desired manner,that herein shown having a rib 6 extending alon the bottom at its rearend and within which a sear or sears 7 are pivotally mounted and thatmay be operated by means of a trigger or other members (not hereinshown) in a manner that will be readily understood `by those skilled inthe art, and the invention forming' the subject matter of thisapplication having to do with the firingl pin only the illustration anddescription erein is suficient for' acorrect understanding of myinvention. i

The firing pin comprises a body 8 that is in the usual form of a rodhaving threaded `ends 9 and 10. A head 11 is secured to the screwthreaded end 10, said head having a neck 12 projecting inwardly andinclosmg a portion of the body of the pin as shown in lFig. 2 ofthe'drawin s. The Sear or sears 7 act against the s Oulder 13 at the endof the neck 12 to hold the rin pin in its cocked position in thebreech-bo t, to

which cocked position it is moved as by means of a lever (not shownherein) which acts against the shoulder 14 at the inner end of the headl1, itv being understood that said lever acts to-move the breech-boltbackwardly in its chamber in thel receiver and at the same time saidlever acts against the shoulder 14 to move the firing pin backwardly inthe breech-bolt until it is engaged by the sear 7 in which position thefringpin is held until released by movement of the sears. The sears areheld in such engagement by means of a spring pressed plunger 15 as shownin Fig. 1 of the drawings. A collar 16 is secured to the body 8 in anysuitable manner and in connection with a retaining pin 17 extendingthrough an opening 18 in the breech-bolt serves to limit the backwardmovement of the ring pin within said bolt. A spring 19 is employed tohold the firing pin at the forward limit of its play in a manner commonto devices of this class. A flange 20 is formed on the body of thefiring pin, this flange having means to receive and retain a lock. Inthe form of construction herein shown this means preferably consists ofslots 21 formed on diametrically opposite sides of the ange 20. A firingtip 22 fits the screw threaded end 9 of the body of the pin and isscrewed up against the flange 20, as shown in Figs. 1 and 2 of thedrawings.

A lock 23 is mounted to slide on the body 8, this lock being in the formof a collar and having locking prongs 24 extending through the slots 21and into notches 25 in the back edge of the firing tip 22, and as shownin Fig. 1 of the drawings. The firing tip is held in its locked positionas by means of the prongs 24 extending from the lock 23 through theslots in the flange 20 on the body 8 and into the recesses 25 in saidtip.

The construction herein illustrated and described provides a very simpleand `dur- Patented Ang. 26, 1919.

that the invention can be carried out by other means.

I claiml 1. A firing pin comprising a body having a threaded end With aflange on said pin and a slot in said flange, a ring tip fitting saidscrew threaded end, a lock mounted on the body, and a member to unitethe lock and firing tip, said member extending through the. slot in saidflange.

2. ring pin comprising a body having a threaded end and a flangeadjacent to said thread and with a slot in said flange, a firing tipfitting the threaded end and 15 having a notch in its edge, and a lockmounted upon the body and having a prong extending through said slot andengaging the notch in the edge of the firing tip.

p 3. A firing pin comprising a body having a thread at one end With aange adjacent to said thread, a firing tip engaging said thread, a lockmounted upon said body, an interengaging member extending between saidlock and tip and passing through a slot in said iange, and a headremovably secured to the opposite end of said pin.
